Can you control the movement of chickens from certain areas

We have a small flock and for most of the day the roam free, we have 2 acres and they can pretty much go anywhere they like. There are jus a few areas that we would like to keep them away from. Like in the garage or on the deck that connects to the house.

Is there a way to discourage the chickens from entering various areas without using fences?
